Abstract
Corrosion hazards in marine environmental construction have been studied. ASTM A36 can be widely used in various industrial sectors and oil extracted offshore. The main objective of this study is to analyze the influence of variation immersion time to corrosion behaviour ASTM A36 by using seawater from Bangka Barat Regency, Bangka Belitung Islands as a corrosive media by performing Brinell hardness test, measurement of weight loss and corrosion rate, and and confirm the data obtained with the formed of microstructure. The results revealed that immersion time of 144 hours produced the highest corrosion rate of 27.97 Mpy and but has the lowest hardness number 136,924 BHN. Microstructural observations found the presence of brownish yellow and black (magnetic Fe3O4) corrosion patterns increased along with the increasing immersion time due to the lack of oxygen concentration during the specimen corrosion process.
